ABSTRACT
An area must be accompanied by the development of resource consumption and pollutant emissions,from the perspective of carrying capacity research,there is a threshold of environmental bearing capacity.The purpose of this book is to clarify the current situation of deficit and surplus in the ecological environment of Beijing-Tianjin-Hebei,and to propose measures and suggestions for improvement.In order to achieve research,ecological footprint method is used to reveal that how much of the natural resources has been used in beijing-tianjin-hebei region and ecological carrying capacity comprehensive index method is used to reflect the natural products and services provided by the ability,ultimately through the difference between the two reactions ecological deficit or surplus,to evaluate the status and trend of the ecological environment of the Beijing-Tianjin-Hebei region,the advantage of the method can be from two angles to relative actual resource environmental bearing capacity.The conclusion of the final study is that the average ecological carrying capacity of Beijing is always lower than that of other regions.the limited supply of natural resources lead to the long-term ecological deficit phenomenon,the ecological deficit is reduced year by year in Beijing,Beijing's social and economic development in recent years and the contradictory relationship between the natural resources is gradually ease;The average ecological carrying capacity of Tianjin is lower than that of other regions.Due to the limited supply of natural resources lead to the phenomenon of long-term ecological deficit;The consumption of natural resources in hebei province mainly depend on coal,oil,energy and agricultural production biological resource consumption,development model still presents the same as in 2010 through the consumption of natural resources of stock to make up for a lack of ecological carrying capacity.Although the overall characteristics of Hebei province's consumption of natural resources have not changed significantly,its internal structure has changed to some extent.In addition,in the urban area of Beijing-Tianjin-Hebei,the air quality has made great progress in recent years under the control of air quality.From the above analysis of water resources,we find that the water ecological footprint in Beijing-Tianjin-Hebei region is generally in deficit,of which Beijing region being the most serious,followed by Tianjin and Hebei.
